Subject: [PATCH] Provide an option to disable entity metadata rewriting
|
|
|
|
The work here is derived from the research and guidance of
|
|
various members of the minecraft community
|
|
|
|
This patch provides the ability to disable entity remapping,
|
|
which creates various incompatability issues with mods, however,
|
|
may also create various issues with mods which do not support this,
|
|
hence why the configuration option is provided
